WILLIAM F. KOCH, OF HILLSIDE, COLORADO.

DETACHABLE RAKE-TOOTH POINT.

Specification of Letters Patent.

Application filed February 9, 1915. Serial No. 7,064.

To all whom it may concern Be it known that I, \VILLIAM F. KooH, acitizen of the United States, residing at Hillside, in the county ofCuster and State of Colorado, have invented certain new and usefulImprovements in Detachable Rake- Tooth Points, of which the following isa specification.

This invention relates to detachable points for the teeth of hay sweepsor the like, and has for its primary object to provide an attachmentwhich will greatly increase the efficiency of sweeps or rakes when beingused on rough or uneven soil.

Another object is to provide a detachable point of this character soshaped, that should the point he forced into engagement with the soil,the action of the same will be to force its way out instead of into thesoil, as has been a common occurrence heretofore.

With these and other objects in view, the invention consist in the novelfeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in the accompanyingdrawings, and claimed.

In the drawings Figure 1 is a plan view of the detachable point;

Fig. 2 is a side elevation;

Fig. 3 is an end elevation;

Fig. 4 is a side elevation showing the device in its operative position,as when in use on a hay sweep tooth.

The detachable point herein shown is adapted to be placed upon the endsof the teeth of hay sweeps or the like, when 00- casion requires, and isadapted to be detachably secured thereto in order that the same may beremoved when it is desired to use the sweep in its simpler form.

The point comprises a shoe, runner or body portion 1, formed of sheetmetal and which is transversely curved throughout its length, in plan,the same being tapered to a point as shown clearly in Fig. 1 of thedrawings. The lower pointed end of the body portion is curved from thepoint thereof to a point intermediate its ends, as shown at 2.

A. flat strip 3 of sheet metal is secured to the inner wall of the bodyportion 1, adjacent the pointed end thereof and extends in spacedparallel relation with the body portion 1 to a point adjacent the upperend of the said body portion.

Transversely curved plates 1 and 5 are secured to the outer marginaledges of the body portion 1 and at their inner edges are secured to thestrip 3, these plates terminating at a point intermediate the ends ofthe body portion 1 and the strip 8.

By providing the brace members 4 and 5 as described, it will be seenthat should the point he forced into engagement withthe soil, plates tand 5 will act in the capacity of mold boards to part. the soil andfacilitate the passage of the point therethrough. It will be furtherseen that because of the substantially triangular shape of the lowerportion of the point, a cutting edge is provided whereby the cuttingaction thereof will be greatly increased.

By providing the body portion 1 with the curved portion 2, it will beapparent that should the point he forced into the ground, the action ofthe curved portion will be to force the point upwardly and consequentlyout of engagement therewith.

In order to provide a means to prevent accidental disengagement of thepoints from the teeth of the sweep or the like, the upper portion of thebody portion 1 may be provided with an opening 6 for receiving a tyingelement such as a chain or the like.

From the foregoing description taken in connection with the accompanyingdrawings it is thought that the construction and operation of the devicewill be clearly understood and while I have herein shown and describedone specific form of my invention I do not Wish to be limited thereto,except for such limitations, as the claims may import.

What is claimed is 1. A rake tooth point comprising a body portionformed of sheet metal, tapered to a point at one end and said taperedportion being curved to form an arcuate ground engaging face, soilplates each having one of their longitudinal edges fixed to said bodyportion to extend longitudinally with respect thereto, said soil platesbeing concaved longitudinally, and a strip to connect the otherlongitudinal edges of said soil plates so as to provide a cutting edge,as and for the purpose specified.

2. In a point for a hay sweep tooth, a device comprising a body portionformed of sheet metal and tapered toward one end to form a point, saidbody portion having its pointed end bent upwardly in the are PatentedFeb. 19, 1918.

of a circle to provide arcuate ground-engaging plates when said toothpoint is in its normal working position on =ahay-sweep,'

: sweep, I a longitudinally and laterally. curved shoe :or runneraflatstrip of a length substantially equal-:to the length of said shoeand extending longitudinally thereof and being inspaced'rel-ationthereto at the rear end; and juxtaposed to said shoe at its front end,and soil-displacing plates each having one .of .-its longitudinal edgessecured (to a lateral edge of said shoe and :having its otherlongitudinal edge secured to one of the major surfaces. of: said strip.

4. I11 a detachable tooth point for a hay sweep having teeth of ordinaryconstruction,--alongitudinally and laterally curved shoe or runner, aflat strip of a length substantially'equalto the length of said shoe andextending longitudinally thereof and "being-in spaced relationthereto'at'the rear endandjuxtaposedthereto at its front end, andsoil-displacing plates each having one of its longitudinal edges securedto. a lateral edge ofsaid shoe and'having itsotherlongitudinal edgesecured toone of the major surfaces of said strip, said-toothpoint-being designedfor connection with means for securing said tooth'pointzinposition on said tooth without .niodification of the latter.

In testimony whereof I affix my signa turein presence of. two.witnesses.
